3M 929800-01-21 Equivalent & Substitute Parts

Part Overview

The 3M 929800-01-21 is a rectangular connector header designed for through-hole mounting applications. This 21-position, single-row connector operates at 0.100" (2.54mm) pitch and is rated for 2.5A current with an operating temperature range of -40°C to 105°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 929800-01-21 is determined by the following critical parameters: 21-position count, 0.100" (2.54mm) mating pitch, male pin contact type, through-hole solder termination, single-row configuration, and board-to-board or board-to-cable style. All identified substitutes meet these core electrical and mechanical requirements. Variations in contact geometry, finish materials, insulation height, and compliance certifications are documented in the parameter comparison table and do not preclude functional equivalence within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The TSW-121-06-T-S (Samtec Inc.) and 335-10-121-00-160000 (Mill-Max Manufacturing Corp.) are both active-status alternatives to the obsolete 929800-01-21. The Samtec TSW-121-06-T-S maintains the closest electrical and mechanical alignment, with identical pitch, position count, and row configuration. This part achieves ROHS3 compliance and extends the operating temperature range to -55°C ~ 105°C, providing enhanced environmental performance. The Mill-Max 335-10-121-00-160000 offers gold-plated contacts and PCT insulation material, suitable for applications requiring enhanced corrosion resistance and higher voltage ratings (100V, 150VDC). Both substitutes are available in active production with documented inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the TSW-121-06-T-S directly replace the 929800-01-21 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (21), row configuration (1), contact type (male pin), and through-hole solder termination. The TSW-121-06-T-S maintains mechanical and electrical compatibility within the specified operating envelope.

Q: What are the key differences between the Samtec and Mill-Max substitutes?

A: The Samtec TSW-121-06-T-S uses square contacts with tin finish and phosphor bronze material. The Mill-Max 335-10-121-00-160000 uses circular contacts with gold finish and brass alloy material. Contact geometry and finish material differences do not affect functional compatibility for standard board-to-board applications.

Q: Does the Mill-Max part offer advantages over the Samtec alternative?

A: The Mill-Max 335-10-121-00-160000 provides gold-plated contacts, which offer enhanced corrosion resistance in high-humidity or corrosive environments. It also specifies voltage ratings (100V, 150VDC) not documented for the original part. The Samtec TSW-121-06-T-S provides a wider operating temperature range (-55°C ~ 105°C versus -40°C ~ 105°C).

Q: Are there packaging considerations when switching to substitute parts?

A: The 929800-01-21 is supplied in bulk packaging. The TSW-121-06-T-S is supplied in bulk packaging, while the 335-10-121-00-160000 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the RoHS compliance status of these substitutes?

A: The original 929800-01-21 is RoHS non-compliant. Both substitute parts (TSW-121-06-T-S and 335-10-121-00-160000) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.
