Substitute Part Grouping Explanation

Substitution for the M20-8771642 is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid equivalency:

Critical Matching Parameters:

Pitch - Mating: 0.100" (2.54mm) — determines physical mating compatibility
Number of Positions: 16 — establishes connector capacity
Number of Rows: 1 — defines physical layout
Contact Type: Male Pin — specifies mating interface
Mounting Type: Surface Mount — ensures PCB assembly compatibility
Termination: Solder — confirms attachment method
Current Rating: 3A per Contact — maintains electrical performance
Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
Material Flammability Rating: UL94 V-0 — meets safety requirements
RoHS Compliance: ROHS3 or equivalent — ensures regulatory alignment

Acceptable Variations:

Connector Type: Header, Cuttable or Header, Breakaway — both support field configuration
Contact Finish - Mating: Gold or Tin — both provide adequate corrosion resistance
Contact Material: Brass or Phosphor Bronze — both support required current ratings
Insulation Material: Polyamide (PA6T/PA9T), Nylon 6T/9T — all provide equivalent mechanical properties
Fastening Type: Push-Pull — consistent across all substitutes

Four active substitute parts meet these criteria and are available from multiple manufacturers.

Frequently Asked Questions (FAQ)

Q: Can M20-8771642R be used as a direct replacement for M20-8771642?

A: Yes. M20-8771642R is the active equivalent from Harwin Inc. with identical pitch (0.100"), position count (16), contact type (male pin), mounting method (surface mount), termination (solder), and operating temperature range (-40°C ~ 105°C). No design modification is required.

Q: What is the difference between cuttable and breakaway header types?

A: Both connector types support field configuration of individual positions. Cuttable headers (M20-8771642, M20-8771642R) allow mechanical separation of positions. Breakaway headers (95293-401-16LF, GBC16SABN-M30, GEC16SABN-M30) provide pre-scored separation points. Both types are functionally equivalent for standard applications.

Q: Can I use a substitute part with a higher operating temperature range?

A: Yes. Parts with extended temperature ranges (95293-401-16LF: -65°C ~ 130°C; GBC16SABN-M30 and GEC16SABN-M30: -65°C ~ 150°C) are fully compatible with applications specified for -40°C ~ 105°C. The higher range provides additional thermal margin without affecting electrical or mechanical performance.

Q: What is the difference between gold and tin mating contact finishes?

A: Both finishes provide adequate corrosion resistance for this connector class. Gold finish (M20-8771642, M20-8771642R, GBC16SABN-M30) offers superior contact resistance stability. Tin finish (95293-401-16LF, GEC16SABN-M30) is cost-effective and suitable for standard applications. Selection depends on application requirements and cost considerations.

Q: Are all substitute parts RoHS compliant?

A: Yes. M20-8771642R, GBC16SABN-M30, and GEC16SABN-M30 are ROHS3 compliant. 95293-401-16LF is RoHS compliant. All parts meet regulatory requirements for lead-free construction.

Q: What is the current rating for each position?

A: All parts, including the main part and all substitutes, are rated for 3A per contact. Total connector current capacity is 48A (16 positions × 3A).

Q: Can I mix and match connector types in the same design?

A: All four substitute parts maintain identical pitch (0.100"), position count (16), and mating interface specifications. They are mechanically and electrically interchangeable within the same PCB design. Contact finish and insulation material differences do not affect interchangeability.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the component requires no special moisture control during storage, handling, or assembly. No baking or desiccant packaging is required prior to soldering.
