5126-B7A2PL Equivalent & Substitute Parts

Part Overview

The 5126-B7A2PL is a 26-position rectangular receptacle connector manufactured by 3M, designed for board-to-board or cable applications. This connector features 0.100" (2.54mm) pitch, through-hole right-angle mounting, and gold-plated contacts rated for 1A at 1000V. The product is active and currently in stock with 1041 units available. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 5126-B7A2PL is determined by the following critical parameters:

Position Count and Pitch: 26 positions at 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
Mounting Configuration: Through-hole, right-angle orientation
Contact System: Gold-plated mating surface with push-pull fastening
Electrical Performance: Current and voltage ratings must meet or exceed application requirements
Thermal Range: Operating temperature compatibility within specified limits
Flammability Compliance: UL94 V-0 material rating

The substitute part SFH11-PBPC-D13-RA-BK meets these core substitution criteria through matching position count, pitch geometry, mounting type, contact finish, and fastening mechanism. Both parts are active products with UL94 V-0 compliance and unlimited moisture sensitivity level (MSL 1).

Engineering Selection Recommendations

Both the 5126-B7A2PL and SFH11-PBPC-D13-RA-BK are active products with identical export classification (EAR99) and unlimited moisture sensitivity ratings. The SFH11-PBPC-D13-RA-BK offers higher current capacity (3A versus 1A) and maintains UL94 V-0 flammability compliance. The primary design consideration is the connector type difference: the 5126-B7A2PL is a receptacle while the SFH11-PBPC-D13-RA-BK is a header. This distinction requires that mating connector types be verified for system compatibility. The operating temperature range of the 5126-B7A2PL extends to -55°C, providing broader low-temperature coverage than the SFH11-PBPC-D13-RA-BK at -40°C minimum. Selection should be based on application temperature requirements and mating connector availability.

Frequently Asked Questions (FAQ)

Q: Can the SFH11-PBPC-D13-RA-BK directly replace the 5126-B7A2PL?

A: Direct mechanical and electrical substitution is possible when the mating connector type is compatible. The 5126-B7A2PL receptacle mates with headers, while the SFH11-PBPC-D13-RA-BK header mates with receptacles. Verify that your system's mating connector type accommodates this interchange.

Q: What are the key matching parameters between these parts?

A: Both connectors share 26 positions, 0.100" (2.54mm) pitch, 2-row configuration, through-hole right-angle mounting, gold-plated mating contacts, push-pull fastening, and UL94 V-0 flammability rating.

Q: Does the higher current rating of the SFH11-PBPC-D13-RA-BK affect compatibility?

A: No. The 3A rating of the SFH11-PBPC-D13-RA-BK exceeds the 1A requirement of the 5126-B7A2PL, making it suitable for applications requiring up to 3A. Current rating is a maximum specification; lower-current applications remain compatible.

Q: Are there temperature range differences I should consider?

A: Yes. The 5126-B7A2PL operates from -55°C to 105°C, while the SFH11-PBPC-D13-RA-BK operates from -40°C to 105°C. Applications requiring operation below -40°C require the 5126-B7A2PL.

Q: What is the packaging difference?

A: The 5126-B7A2PL is supplied in bulk packaging, while the SFH11-PBPC-D13-RA-BK is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: The SFH11-PBPC-D13-RA-BK is explicitly marked as ROHS3 Compliant and REACH Unaffected. Compliance status for the 5126-B7A2PL is not provided in the available specifications.
