Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2-282812-1 are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Number of Positions: 21 (exact match required)
• Header Type: Male Pins, Shrouded (2 Side) (exact match required)
• Header Orientation: 90°, Right Angle (exact match required)
• Termination Style: Solder (exact match required)
• Mounting Type: Through Hole (exact match required)
• Current Rating - UL: 15 A (exact match required)
• Voltage Rating - UL: 300 V (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)

Allowable Variations:

• Pitch: 0.197" (5.00mm) to 0.200" (5.08mm) — minor pitch tolerance acceptable for mechanical fit
• Operating Temperature: -40°C ~ 110°C to -40°C ~ 105°C — acceptable variation within industrial range
• Contact Material: Copper Alloy to Brass — both acceptable for electrical performance
• Housing Material: Polyamide (PA66) to Polybutylene Terephthalate (PBT) — both acceptable thermoplastic materials
• Contact Tail Length: 0.138" (3.50mm) to 0.155" (3.94mm) — acceptable variation for through-hole PCB mounting
• Insulation Height: 0.329" (8.36mm) to 0.319" (8.10mm) — acceptable variation within mechanical tolerance

Engineering Selection Recommendations

Primary Substitute: Molex 0395320021

The Molex 0395320021 terminal block header is the primary substitute for the obsolete TE Connectivity 2-282812-1. This part maintains all critical electrical and mechanical parameters including 21-position configuration, 15 A UL current rating, 300 V UL voltage rating, UL94 V-0 flammability rating, and through-hole solder termination. The part is currently in active production status, ensuring long-term availability. The pitch variation from 5.00mm to 5.08mm is within acceptable mechanical tolerance for standard PCB layouts. ROHS3 compliance is maintained. Inventory availability is 930 pieces.

Secondary Substitute: Amphenol PCD ELFH21220

The Amphenol PCD ELFH21220 terminal block header serves as a secondary substitute option. This part meets all critical electrical specifications and maintains the 21-position, 90° right-angle configuration with 15 A UL and 300 V UL ratings. The housing material differs (PBT versus PA66), providing enhanced thermal stability. The part is in active production status with RoHS compliance. Inventory availability is 775 pieces. The contact tail length is slightly longer (0.155" versus 0.138"), which may require PCB layout verification for through-hole mounting depth.

Compliance Considerations:

Both substitute parts maintain ROHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial applications. The MSL rating of 1 (Unlimited) for all parts indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395320021 be used as a direct replacement for the TE Connectivity 2-282812-1?

A: The Molex 0395320021 is functionally compatible as a substitute. The pitch difference of 0.003" (0.08mm) is within standard PCB manufacturing tolerance. Both parts share identical electrical ratings (15 A, 300 V), connector type (21-position male header, shrouded), and termination method (solder through-hole). Mechanical fit on existing PCBs designed for the original part requires verification of pad spacing tolerance.

Q: What is the difference between the Molex and Amphenol PCD substitute options?

A: Both parts meet identical electrical specifications and connector configuration requirements. The primary differences are: (1) Housing material — Molex uses PA66 nylon while Amphenol uses PBT, offering different thermal and chemical resistance profiles; (2) Contact tail length — Amphenol's longer tail (0.155" versus 0.150") may affect through-hole insertion depth; (3) Insulation height — minor variation of 0.008" between parts. Selection depends on specific PCB design constraints and environmental operating conditions.

Q: Are there any compatibility issues with the pitch variation between 5.00mm and 5.08mm?

A: The pitch variation of 0.08mm represents a 1.6% difference. For standard PCB manufacturing with typical pad spacing tolerances of ±0.05mm, this variation is acceptable. However, applications with tightly constrained mechanical spacing or custom PCB designs should verify pad-to-pad distances before implementation. Standard industrial PCB design practices accommodate this tolerance range.

Q: Do all substitute parts maintain the same operating temperature range?

A: The TE Connectivity original part operates from -40°C to 110°C. Both Molex and Amphenol substitutes operate from -40°C to 105°C. The 5°C reduction in maximum operating temperature is within acceptable limits for most industrial applications. Applications requiring operation above 105°C require design review.

Q: What is the significance of the contact material difference (Copper Alloy versus Brass)?

A: Both copper alloy and brass provide equivalent electrical conductivity and contact performance for 15 A applications. Brass offers enhanced corrosion resistance in certain environmental conditions. The tin mating finish on both materials ensures equivalent solder joint reliability and electrical connection quality.

Q: Are the substitute parts available in the same packaging as the original?

A: The TE Connectivity 2-282812-1 packaging is not specified in available data. The Molex 0395320021 is supplied in bulk packaging, while the Amphenol PCD ELFH21220 is supplied in tray packaging. Packaging selection depends on procurement volume and handling requirements for manufacturing operations.

Q: What compliance certifications apply to all parts in this substitution group?

A: All parts maintain UL94 V-0 flammability certification and RoHS compliance (ROHS3 for TE and Molex; RoHS for Amphenol). All parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. ECCN classification is EAR99 for all parts, and HTSUS code 8536.69.4040 applies uniformly.
