Key Parameters

Substitute Part Grouping Explanation

Substitution for the M50-3501642 is determined by the following critical parameters:

• Pitch and Position Configuration: Mating pitch of 0.050" (1.27mm), 32 positions in 2 rows with 0.050" row spacing
• Connector Interface: Male pin header, unshrouded, board-to-board or cable style
• Mounting and Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: Minimum 1A current rating per contact, gold-plated mating surface
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliant, operating range -40°C to 105°C or better

Two substitute parts meet these criteria:

1. M50-3500842 (Harwin Inc.): Same series, same pitch and row spacing, but reduced to 16 positions. Maintains identical electrical and mechanical interface characteristics.

2. FTS-116-01-L-D (Samtec Inc.): Direct 32-position equivalent with identical pitch configuration. Offers enhanced electrical performance and extended operating temperature range.

Engineering Selection Recommendations

For Direct Replacement (32-Position Requirement):

The FTS-116-01-L-D from Samtec Inc. is the primary direct substitute for the M50-3501642. Both connectors maintain identical position count, pitch, and row spacing. The FTS-116-01-L-D is an active product with superior electrical performance (3.4A per contact versus 1A) and extended operating temperature range (-55°C to 125°C). The cuttable feature provides additional design flexibility. Both parts are ROHS3 compliant and REACH unaffected.

For Reduced Position Requirement (16-Position Alternative):

The M50-3500842 from Harwin Inc. remains within the same product family and maintains identical pitch and row spacing characteristics. This option is suitable when circuit design permits reduction to 16 positions. The part is active in production with equivalent electrical specifications and environmental ratings to the original M50-3501642.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability certification, ROHS3 compliance, and REACH unaffected status, ensuring regulatory continuity with the original design.

Frequently Asked Questions (FAQ)

Q: Can M50-3500842 be used as a direct replacement for M50-3501642?

A: M50-3500842 is mechanically and electrically compatible but provides only 16 positions instead of 32. Use this substitute only if your circuit design can operate with reduced position count. The pitch, row spacing, mounting type, and termination method are identical.

Q: What are the key differences between FTS-116-01-L-D and M50-3501642?

A: Both connectors provide 32 positions at 0.050" (1.27mm) pitch with identical row spacing and mounting characteristics. FTS-116-01-L-D offers higher current rating per contact (3.4A versus 1A), extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), and includes a cuttable feature. Contact material differs (phosphor bronze versus copper alloy) and insulation material is liquid crystal polymer (LCP) versus thermoplastic.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. M50-3500842 and FTS-116-01-L-D are both ROHS3 compliant and REACH unaffected, matching the compliance status of the original M50-3501642.

Q: Can the FTS-116-01-L-D cuttable feature be used in my application?

A: The cuttable feature allows the connector to be separated into smaller position counts if required by your circuit layout. This is an optional capability; the connector functions as a standard 32-position header if not utilized.

Q: What is the inventory status of these substitute parts?

A: M50-3500842 has 8013 pieces in stock. FTS-116-01-L-D has 824 pieces in stock. The original M50-3501642 has 1100 pieces available but is obsolete.
