HTMS-108-02-G-S-RA Equivalent & Substitute Parts

Part Overview

The HTMS-108-02-G-S-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board applications. This 8-position connector operates at 0.050" (1.27mm) pitch and is rated for 5A per contact with an operating temperature range of -55°C to 125°C. The part is currently active in production and RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the core specifications, enabling component interchangeability in applications where the original part may be unavailable or require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the HTMS-108-02-G-S-RA is determined by strict alignment of the following core parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 8
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part 5-104186-5 (TE Connectivity AMP Connectors) meets all mandatory substitution criteria. Both parts share identical pitch, position count, row configuration, mounting orientation, termination method, and fastening mechanism. Both are unshrouded headers with UL94 V-0 flammability ratings and RoHS3 compliance, confirming functional and regulatory equivalence for board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTMS-108-02-G-S-RA and 5-104186-5 are active production parts with RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific requirements not covered by the core substitution parameters.

The HTMS-108-02-G-S-RA operates across a wider temperature range (-55°C to 125°C) compared to the 5-104186-5 (-65°C to 105°C). Applications requiring sustained operation above 105°C or below -55°C should specify the Samtec part.

The HTMS-108-02-G-S-RA provides a documented current rating of 5A per contact, while the 5-104186-5 does not specify current rating in the provided data. Applications with defined current requirements should reference the Samtec specification.

Both parts carry MSL 1 (Unlimited) moisture sensitivity, indicating no special storage or handling requirements. Both are suitable for general purpose, automotive, medical, and telecommunications applications where board-to-board connectivity is required.

Frequently Asked Questions (FAQ)

Q: Can the 5-104186-5 be used as a direct replacement for the HTMS-108-02-G-S-RA?

A: Yes, for applications operating within the 5-104186-5 temperature range (-65°C to 105°C) and where current requirements do not exceed the undocumented rating of the TE Connectivity part. Both connectors share identical pitch (0.050"), position count (8), mounting type (through-hole right-angle), and fastening mechanism (push-pull), confirming mechanical and electrical compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are contact geometry (square vs. circular), contact material (phosphor bronze vs. copper alloy), insulation material (LCP vs. thermoplastic), operating temperature range, and current rating documentation. The HTMS-108-02-G-S-RA supports a wider temperature range and specifies 5A per contact.

Q: Are both parts RoHS3 compliant?

A: Yes, both the HTMS-108-02-G-S-RA and 5-104186-5 are RoHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices are sufficient.

Q: Do these connectors require any special packaging considerations?

A: Both parts are supplied in tube packaging. No special handling beyond standard component storage is required given their MSL 1 rating.
