Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 86453-032LF are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - Mating (0.079" / 2.00mm)
• Number of positions (32)
• Number of rows (2)
• Row spacing (0.079" / 2.00mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact material (Phosphor Bronze)

Identified Substitutes:

1. TMMH-116-01-F-D-RA (Samtec Inc.) — Direct pitch and position match with identical mating specifications. Active product status. Cuttable header design. Insulation material differs (LCP vs. PA/Nylon). Operating temperature range expanded (-55°C ~ 125°C). RoHS3 compliant.

2. HMTSW-116-08-L-D-200-RA (Samtec Inc.) — Pitch differs at 0.100" (2.54mm) with expanded position capability. Not a direct substitute due to pitch incompatibility with 2.00mm mating surfaces. Listed for reference only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TMMH-116-01-F-D-RA

This part maintains full electrical and mechanical compatibility with the 86453-032LF. Both components share identical pitch (0.079" / 2.00mm), position count (32), row configuration (2 rows), and row spacing. The TMMH-116-01-F-D-RA is an active product with RoHS3 compliance, addressing the obsolescence of the original part. The expanded operating temperature range (-55°C ~ 125°C) provides additional thermal margin. Insulation material differs (LCP vs. PA/Nylon), but both meet UL94 V-0 flammability requirements. The cuttable header design offers design flexibility for custom configurations.

Secondary Reference: HMTSW-116-08-L-D-200-RA

This part is not recommended as a direct substitute due to pitch incompatibility (0.100" / 2.54mm vs. 0.079" / 2.00mm). Mating surface spacing differs, preventing direct connection with existing 2.00mm pitch receptacles. This part is listed for reference only in applications requiring different pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can the TMMH-116-01-F-D-RA directly replace the 86453-032LF in existing designs?

A: Yes. Both parts share identical mating pitch (0.079" / 2.00mm), position count (32), row configuration, and row spacing. Mechanical and electrical compatibility is maintained. The primary difference is insulation material (LCP vs. PA/Nylon), which does not affect connector function in standard applications.

Q: What is the significance of the cuttable header design in the TMMH-116-01-F-D-RA?

A: The cuttable design allows the header strip to be segmented into smaller connector configurations without compromising electrical or mechanical performance. This provides design flexibility for applications requiring custom position counts.

Q: Why is the HMTSW-116-08-L-D-200-RA not suitable as a substitute?

A: The HMTSW-116-08-L-D-200-RA operates at 0.100" (2.54mm) pitch, which is incompatible with the 0.079" (2.00mm) mating surfaces of the original design. Pitch mismatch prevents proper connector engagement and electrical contact.

Q: Are there compliance differences between the main part and the TMMH-116-01-F-D-RA?

A: The TMMH-116-01-F-D-RA carries RoHS3 compliance certification, addressing modern regulatory requirements. Both parts meet UL94 V-0 flammability standards. The TMMH-116-01-F-D-RA has MSL 1 (Unlimited), matching the original part's moisture sensitivity classification.

Q: What is the inventory status for the recommended substitute?

A: The TMMH-116-01-F-D-RA is an active product with 1260 pieces in stock, providing reliable procurement availability compared to the obsolete 86453-032LF.
