Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: mating pitch (0.100" / 2.54mm), number of positions (16), number of rows (2), row spacing (0.100" / 2.54mm), contact type (male pin), mounting type (through hole), termination method (solder), and material flammability rating (UL94 V-0). All identified substitute parts meet these mandatory criteria. Variations in contact length, insulation height, contact material composition, and contact finish thickness are permitted within the scope of board-to-board or board-to-cable applications. Operating temperature range, current rating, and compliance certifications (RoHS3, MSL 1) are documented for each substitute to support design validation and supply chain decisions.

Engineering Selection Recommendations

All substitute parts listed maintain active product status except Molex 0751020046, which is discontinued at DiGi Electronics and should be avoided for new designs requiring long-term availability. The Amphenol ICC BERGSTIK series (77313-101-16LF, 77313-118-16LF, 77313-418-16LF, 77313-801-16LF, 77313-818-16LF) provides the widest operating temperature range (-65°C to 130°C) and is suitable for applications requiring extended thermal performance beyond the M20-9980845 specification. The Molex C-Grid 70280 (0010897162) and C-Grid III 90131 (0901310928) series offer ROHS3 compliance and active production status with adequate inventory levels. The Hirose A1-16PA-2.54DSA(71) provides ROHS3 compliance and a 200V voltage rating specification. The Samtec BBD-108-G-A operates across -55°C to 125°C and maintains ROHS3 compliance. Selection should prioritize active product status, compliance certifications (ROHS3 or RoHS), and operating temperature requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the M20-9980845?

A: The mandatory parameters are 0.100" (2.54mm) mating pitch, 16 positions, 2 rows, 0.100" (2.54mm) row spacing, male pin contact type, through-hole mounting, solder termination, and UL94 V-0 flammability rating. All listed substitutes meet these criteria.

Q: Can I use the Molex 0751020046 in a new design?

A: The Molex 0751020046 is discontinued at DiGi Electronics and should not be selected for new designs. Active alternatives include the Molex C-Grid 70280 (0010897162) or C-Grid III 90131 (0901310928).

Q: What is the difference between the Amphenol ICC BERGSTIK variants (77313-101-16LF, 77313-118-16LF, 77313-418-16LF, 77313-801-16LF, 77313-818-16LF)?

A: The variants differ in contact post length and contact finish specifications. The 77313-101-16LF and 77313-801-16LF have 0.095" (2.41mm) post length, while 77313-118-16LF, 77313-418-16LF, and 77313-818-16LF have 0.120" (3.05mm) post length. The 77313-418-16LF uses tin mating finish instead of gold. All operate at -65°C to 130°C with 3A per contact rating.

Q: Does the Hirose A1-16PA-2.54DSA(71) have a voltage rating specification?

A: Yes, the Hirose A1-16PA-2.54DSA(71) is rated for 200V, which is specified in the product data. The M20-9980845 does not include a voltage rating specification.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are RoHS compliant. The M20-9980845, Molex 0010897162, Molex 0901310928, Hirose A1-16PA-2.54DSA(71), and Samtec BBD-108-G-A are ROHS3 compliant. The Amphenol ICC BERGSTIK series (77313-101-16LF, 77313-118-16LF, 77313-418-16LF, 77313-801-16LF, 77313-818-16LF) are RoHS compliant.

Q: What is the operating temperature range for each substitute?

A: The M20-9980845 operates at -40°C to 105°C. The Amphenol ICC BERGSTIK series extends to -65°C to 130°C. The Hirose A1-16PA-2.54DSA(71) operates at -55°C to 85°C. The Samtec BBD-108-G-A operates at -55°C to 125°C. Molex parts do not specify operating temperature in the provided data.

Q: Can I mix contact materials between the M20-9980845 and substitute parts?

A: Contact material variations (brass, copper alloy, phosphor bronze) are permitted within the scope of substitution. All materials maintain the required electrical and mechanical performance for 0.100" (2.54mm) pitch 16-position connectors with solder termination.

Q: What packaging options are available?

A: The M20-9980845 is supplied in bulk packaging. Substitute parts are available in bulk (Molex 0010897162, Amphenol ICC BERGSTIK series), tray (Molex 0901310928, Hirose A1-16PA-2.54DSA(71)), or tube (Samtec BBD-108-G-A) packaging.
