WR-PHD PIN HEADER 1.27 MM SMT (62101021021)

Part Overview

The Würth Elektronik 62101021021 is a rectangular connector header designed for surface mount applications. This WR-PHD series connector features a 1.27 mm pitch configuration with 10 positions arranged in 2 rows, providing board-to-board connectivity with male pin contacts. The component is currently active in production and maintains full inventory availability. Alternative equivalent parts may be required due to supply chain considerations, design flexibility, or specific application requirements where substitute connectors meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR-PHD 62101021021 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header with male pin contacts
• Mounting Type: Surface Mount (SMT)
• Termination Method: Solder
• Number of Positions: 10 positions in 2 rows
• Pitch Configuration: 0.050" (1.27mm) mating pitch and row spacing
• Contact Length - Mating: 0.150" (3.81mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold plating
• Fastening Type: Push-Pull mechanism
• Shrouding: Unshrouded design
• Style: Board to Board connectivity

Compliance and Environmental Criteria:

• Material Flammability: UL94 V-0 rating
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must maintain compatibility across all primary matching criteria to ensure functional equivalence in board-level applications. Variations in secondary parameters such as insulation material composition, contact material base (copper alloy versus phosphor bronze), or operating temperature ranges do not preclude substitution when primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

FTSH-105-04-F-DV (Samtec Inc.) - Primary Equivalent

The Samtec FTSH-105-04-F-DV represents the closest functional equivalent to the WR-PHD 62101021021. Both connectors share identical pitch specifications (0.050" / 1.27mm), position count (10 positions in 2 rows), contact geometry (square male pins with 0.150" mating length), and gold-plated mating surfaces. Both components maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. The Samtec part features an extended operating temperature range (-55°C ~ 125°C) compared to the Würth part (-40°C ~ 105°C), providing broader thermal performance capability. The FTSH series incorporates Liquid Crystal Polymer insulation material and phosphor bronze contact material, both established alternatives to the Würth part's polyamide and copper alloy construction. All three components are active products with confirmed inventory availability.

0877591015 (Molex) - Limited Compatibility

The Molex 0877591015 from the Milli-Grid 87759 series shares the same 10-position, 2-row configuration and surface mount solder termination as the WR-PHD 62101021021. However, the Molex connector operates at a 0.079" (2.00mm) pitch specification, which differs from the 1.27mm pitch of the primary part. This pitch difference results in incompatible mating footprints and contact spacing, preventing direct substitution in applications designed for 1.27mm pitch connectors. The Molex part is suitable only for applications where 2.00mm pitch specifications are acceptable. Both the Molex and Würth connectors maintain identical contact length (0.150"), insulation height (0.059"), UL94 V-0 rating, and ROHS3 compliance.

Selection Basis

Component selection should prioritize the Samtec FTSH-105-04-F-DV when direct pitch-compatible substitution is required. The Molex 0877591015 is applicable only in applications where the 2.00mm pitch specification aligns with design requirements. All three connectors satisfy regulatory compliance requirements and environmental classifications specified for the WR-PHD series.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0877591015 be used as a direct replacement for the Würth 62101021021?

A: No. The Molex 0877591015 operates at 0.079" (2.00mm) pitch, while the Würth part operates at 0.050" (1.27mm) pitch. These different pitch specifications result in incompatible contact spacing and mating footprints. Direct substitution is not possible without redesigning the mating connector interface and PCB layout.

Q: Is the Samtec FTSH-105-04-F-DV fully compatible with the WR-PHD 62101021021?

A: Yes. Both connectors share identical pitch (0.050" / 1.27mm), position count (10 in 2 rows), contact length (0.150"), contact shape (square), mating surface finish (gold), and fastening mechanism (push-pull). Both maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity. The Samtec part provides an extended operating temperature range and alternative insulation material composition, both of which are compatible with the primary application requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: connector type (header), contact type (male pin), pitch specification (0.050" / 1.27mm), position count (10 positions in 2 rows), row spacing (0.050" / 1.27mm), mounting type (surface mount), termination method (solder), contact length (0.150"), contact shape (square), mating surface finish (gold), fastening type (push-pull), and shrouding configuration (unshrouded). Compliance parameters include UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 moisture sensitivity.

Q: Do differences in insulation material affect substitution compatibility?

A: Insulation material differences do not preclude substitution when all primary electrical and mechanical parameters align. The WR-PHD uses polyamide (PA9T) nylon, while the Samtec FTSH uses Liquid Crystal Polymer (LCP). Both materials satisfy UL94 V-0 flammability requirements and maintain equivalent electrical performance in board-level applications.

Q: Are there current or voltage rating differences between the substitute parts?

A: The WR-PHD 62101021021 specifies 1A current rating and 100VAC voltage rating. The Molex 0877591015 does not provide current or voltage specifications in available documentation. The Samtec FTSH-105-04-F-DV specifies 3.4A per contact, which exceeds the Würth part's 1A rating. When voltage specifications are not provided for substitute parts, design validation against application requirements is necessary.

Q: What is the significance of the extended operating temperature range in the Samtec part?

A: The Samtec FTSH-105-04-F-DV operates across -55°C to 125°C, compared to the Würth part's -40°C to 105°C range. This extended range provides additional thermal margin for applications operating at temperature extremes. However, substitution is valid only when the application's actual operating temperature requirements fall within both specified ranges or when the extended range of the substitute part provides beneficial design flexibility.

Q: Are all three connectors currently in active production?

A: Yes. The WR-PHD 62101021021 (Würth Elektronik), 0877591015 (Molex), and FTSH-105-04-F-DV (Samtec Inc.) are all listed as active products with confirmed inventory availability. Active product status ensures continued availability for procurement and design implementation.
