Key Parameters

Substitute Part Grouping Explanation

Substitution of the 86453-044LF requires strict alignment with core electrical and mechanical parameters. The primary substitution candidate is the Samtec Inc. HTSW-122-08-L-D-RA, which maintains functional equivalence through the following critical parameters:

Matching Parameters:

• Connector type: Header with male pin contacts
• Number of positions: 44 total positions in 2-row configuration
• Mounting style: Through-hole, right-angle orientation
• Termination method: Solder
• Fastening mechanism: Push-pull
• Contact material: Phosphor bronze with gold mating finish
• Flammability rating: UL94 V-0
• Board-to-board or cable application compatibility

Parameter Variance: The HTSW-122-08-L-D-RA operates at a different pitch specification (0.100" / 2.54mm versus 0.079" / 2.00mm), which represents a fundamental mechanical difference. This pitch variance requires physical board layout compatibility verification before substitution. The substitute part also features an extended operating temperature range (-55°C ~ 125°C) and uses Liquid Crystal Polymer (LCP) insulation material instead of glass-filled polyamide, both of which represent performance enhancements.

Parameter Comparison

Engineering Selection Recommendations

The Samtec Inc. HTSW-122-08-L-D-RA represents an active product with current manufacturing support, addressing the obsolescence status of the 86453-044LF. Both components maintain UL94 V-0 flammability compliance and equivalent electrical performance characteristics for standard applications.

Selection of the HTSW-122-08-L-D-RA requires confirmation that the 0.100" (2.54mm) pitch specification is compatible with existing printed circuit board layouts designed for the original 0.079" (2.00mm) pitch component. The extended operating temperature range of the substitute part (-55°C ~ 125°C versus -40°C ~ 105°C) provides additional thermal margin for demanding environments. The Liquid Crystal Polymer insulation material in the substitute offers enhanced dimensional stability compared to glass-filled polyamide.

Frequently Asked Questions (FAQ)

Q: Can the HTSW-122-08-L-D-RA be used as a direct replacement for the 86453-044LF?

A: Functional substitution is possible provided that printed circuit board layouts accommodate the different pitch specification. The 0.100" (2.54mm) pitch of the HTSW-122-08-L-D-RA differs from the 0.079" (2.00mm) pitch of the original component, requiring physical board compatibility verification.

Q: What are the primary electrical differences between these components?

A: Both components maintain equivalent electrical performance with gold-plated phosphor bronze contacts, push-pull fastening, and solder termination. The substitute part does not specify a current rating by wire gauge, whereas the original component is rated at 2A (AC/DC). Voltage rating information is not provided for the substitute part.

Q: Are there compliance or certification differences?

A: Both components meet UL94 V-0 flammability requirements. The original component specifies MSL 1 (Unlimited) moisture sensitivity. The substitute part is RoHS3 compliant and lists moisture sensitivity as not applicable.

Q: What is the primary reason to consider substitution?

A: The 86453-044LF is classified as obsolete, making the active-status HTSW-122-08-L-D-RA necessary for ongoing supply chain continuity and new design implementations.

Q: How do the insulation materials compare?

A: The original component uses glass-filled polyamide (PA) nylon insulation, while the substitute employs Liquid Crystal Polymer (LCP). LCP provides superior dimensional stability and moisture resistance characteristics.
