Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-115-04-L-D-RA is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 30 positions in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle configuration
• Shrouding Design: Shrouded with 4-wall construction
• Termination Method: Solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Finish: Gold-plated mating surface with tin-plated posts
• Compliance & Certifications: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The substitute part N2530-5002-RB from 3M meets these core substitution criteria while maintaining functional equivalence for standard board-to-cable interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-115-04-L-D-RA and N2530-5002-RB maintain Active product status and comply with RoHS and UL94 V-0 flammability requirements. Selection between these parts should be based on the following provided specifications:

HTST-115-04-L-D-RA (Samtec Inc.) is suitable when:

• Operating temperature range extends to 125°C
• Current requirements approach or exceed 1.75A per contact
• Phosphor bronze contact material is specified in design requirements

N2530-5002-RB (3M) is suitable when:

• Operating temperature range does not exceed 105°C
• Current requirements remain at or below 1.75A per contact
• Thicker gold plating (30.0µin vs. 10.0µin) is beneficial for contact durability
• PCT/polyester insulation material is compatible with application requirements

Both parts share identical mechanical pitch, row configuration, shrouding design, and fastening mechanism, ensuring PCB footprint compatibility and mating interface standardization.

Frequently Asked Questions (FAQ)

Q: Can N2530-5002-RB replace HTST-115-04-L-D-RA in all applications?

A: Substitution is valid only when operating temperature does not exceed 105°C and current per contact remains at or below 1.75A. The HTST-115-04-L-D-RA is rated to 125°C and 3.4A per contact. Verify application requirements before substitution.

Q: What are the mechanical compatibility considerations?

A: Both connectors share 0.100" (2.54mm) pitch, 2-row 30-position configuration, through-hole right-angle mounting, and 4-wall shrouding. Contact length variations (mating and post) fall within standard tolerance ranges for this connector class and do not affect PCB footprint or mating interface compatibility.

Q: How do the insulation materials differ?

A: HTST-115-04-L-D-RA uses Liquid Crystal Polymer (LCP), while N2530-5002-RB uses PCT with polyester and glass filler. Both materials achieve UL94 V-0 flammability rating. Material selection should align with specific environmental and chemical exposure requirements of the application.

Q: What is the significance of contact finish thickness differences?

A: HTST-115-04-L-D-RA has 10.0µin (0.25µm) gold plating on mating contacts, while N2530-5002-RB has 30.0µin (0.76µm). Thicker plating on the 3M part provides enhanced contact durability and wear resistance in high-cycle mating applications. Both meet standard gold plating specifications for connector applications.

Q: Are there packaging differences between these parts?

A: HTST-115-04-L-D-RA is supplied in Tube packaging, while N2530-5002-RB is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance but may influence inventory management and handling procedures.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant, UL94 V-0 rated, MSL 1 (Unlimited moisture sensitivity), and REACH Unaffected. Both carry ECCN EAR99 classification and HTSUS code 8536.69.4040.
