TE Connectivity 825437-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 825437-2 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle 2-position connector operates at 0.100" (2.54mm) pitch and is designed for board-to-board or cable applications. The connector features male pins with gold-plated mating contacts and tin-plated posts, rated for 5A continuous current operation across an extended temperature range of -65°C to 105°C.

The 825437-2 maintains Active product status with full RoHS compliance and UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 825437-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 2
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Contact Length - Mating: Variation permitted within mechanical envelope constraints
• Contact Length - Post: Variation permitted within solder joint requirements
• Insulation Height: Variation permitted within board clearance constraints
• Contact Finish - Mating: Variation permitted (Gold or Tin acceptable for equivalent electrical performance)
• Contact Finish Thickness: Variation permitted within corrosion protection requirements
• Insulation Material: Variation permitted (PBT, Polyamide, or Polyester acceptable)
• Insulation Color: Variation permitted
• Operating Temperature: Variation permitted if equal to or exceeding original specification
• Current Rating: Variation permitted if equal to or exceeding original specification

All three identified substitute parts meet these criteria and are classified as direct equivalents.

Engineering Selection Recommendations

Primary Selection: TE Connectivity 825437-2

The original TE Connectivity 825437-2 remains the preferred component for new designs and direct replacement applications. This part maintains Active product status with confirmed RoHS compliance and established supply availability of 848 pieces in stock. The gold-plated mating contacts provide enhanced corrosion resistance and contact reliability across the full operating temperature range of -65°C to 105°C.

Substitute Selection: Molex 0901210762

The Molex 0901210762 (C-Grid III 90121 series) is the optimal substitute when the primary part is unavailable. This part matches the original specification in all critical parameters including contact geometry, pitch, mounting configuration, and flammability rating. The gold-plated mating contacts align with the original design intent for corrosion protection. ROHS3 compliance and REACH Unaffected status provide regulatory alignment. Current inventory of 3,786 pieces supports immediate procurement.

Secondary Substitute: Molex 0901210122

The Molex 0901210122 (C-Grid III 90121 series, Tray packaging) provides an alternative when bulk packaging is not required. This part meets all mandatory electrical and mechanical parameters with tin-plated mating contacts. ROHS3 compliance and REACH Unaffected status are confirmed. Inventory of 17,424 pieces in tray packaging supports applications requiring smaller order quantities.

Tertiary Substitute: Molex 0022286020

The Molex 0022286020 (KK254, 42376 series) functions as a substitute when alternative insulation materials and contact geometries are acceptable within the application envelope. This part features tin-plated mating contacts and polyamide insulation material. ROHS3 compliance and REACH Unaffected status are confirmed. Inventory of 32,554 pieces provides maximum availability. The increased mating contact length of 0.361" (9.17mm) requires verification against application clearance constraints.

All substitute parts maintain UL94 V-0 flammability rating, MSL 1 (Unlimited) moisture sensitivity, and EAR99 export classification consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901210762 directly replace the TE Connectivity 825437-2 in existing assemblies?

A: Yes. The Molex 0901210762 matches all mandatory parameters including 2.54mm pitch, 2-position configuration, through-hole right-angle mounting, square contact geometry, and UL94 V-0 flammability rating. Contact length variations of 0.266" (6.75mm) mating and 0.114" (2.90mm) post are within acceptable mechanical tolerances for standard PCB applications. Gold-plated mating contacts provide equivalent corrosion protection to the original specification.

Q: What is the primary difference between the three Molex substitutes?

A: The Molex 0901210762 and 0901210122 are both from the C-Grid III 90121 series with identical electrical and mechanical specifications, differing only in packaging (Bulk vs. Tray) and inventory availability. The Molex 0022286020 from the KK254 series features increased mating contact length (0.361" vs. 0.266") and polyamide insulation material instead of polyester, requiring application-specific clearance verification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification. The original TE Connectivity 825437-2 is RoHS Compliant. All parts meet current RoHS requirements for lead-free solder compatibility and restricted substance limitations.

Q: Does contact finish (Gold vs. Tin) affect substitution eligibility?

A: Contact finish variation is permitted within the substitution criteria. The original TE Connectivity 825437-2 features gold-plated mating contacts. The Molex 0901210762 also provides gold plating, ensuring equivalent corrosion resistance. The Molex 0901210122 and 0022286020 feature tin-plated mating contacts, which provide acceptable electrical performance for standard applications but with different corrosion protection characteristics. Application environment and expected service life determine whether tin-plated alternatives are suitable.

Q: What is the significance of the 5A current rating on the TE Connectivity 825437-2?

A: The 5A current rating specifies the maximum continuous current the connector can safely conduct without exceeding temperature rise limits. The Molex substitute parts do not specify current ratings in the provided data. For applications requiring explicit current rating confirmation, the TE Connectivity 825437-2 or Molex 0901210762 (with documented equivalent performance) are preferred selections.

Q: Can the Molex 0022286020 be used in applications with tight PCB clearance?

A: The Molex 0022286020 features an insulation height of 0.090" (2.29mm), which is lower than the original 0.100" (2.54mm). However, the mating contact length is 0.361" (9.17mm), significantly longer than the original 0.264" (6.70mm). Applications with restricted vertical clearance above the connector must verify that the increased contact length does not interfere with mating connector positioning or adjacent components.

Q: Are all parts suitable for automotive applications?

A: The Molex 0022286020 explicitly lists Automotive applications in its specification. The Molex 0901210762 and 0901210122 list Automotive and General Purpose applications. The TE Connectivity 825437-2 does not specify applications in the provided data. For automotive-specific requirements, the Molex parts with explicit automotive designation provide documented suitability.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both RoHS and ROHS3 represent compliance with Restriction of Hazardous Substances directives. ROHS3 refers to the current iteration of the RoHS 2 directive (2011/65/EU as amended). All parts in this comparison meet current lead-free and restricted substance requirements. The designation difference reflects regulatory evolution but does not indicate functional or electrical differences.
