Key Parameters

Substitute Part Grouping Explanation

The N2530-6V0C-RB-WF from 3M qualifies as an equivalent substitute based on the following critical parameters:

• Connector Configuration: Both parts are 30-position, 2-row headers with identical 0.100" (2.54mm) mating pitch and row spacing
• Mounting and Fastening: Both use surface mount technology with push-pull fastening mechanisms
• Shrouding Design: Both feature shrouded 4-wall construction for keying and mechanical protection
• Electrical Performance: Both support the same contact configuration with male pins and solder termination
• Environmental Compliance: Both meet UL94 V-0 flammability rating and operate across the -55°C to 105°C temperature range
• Regulatory Status: Both are RoHS compliant and carry EAR99 ECCN classification

Substitution is valid when the application does not impose constraints on current rating differences, contact finish specifications, or insulation material composition.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-115-01-T-DV and N2530-6V0C-RB-WF are active production parts with equivalent mechanical and electrical compatibility for standard 30-position, 2-row header applications. Selection between these parts should be based on:

Current Rating Considerations: The HTST-115-01-T-DV supports 3.4A per contact, while the N2530-6V0C-RB-WF supports 1.75A per contact. Applications requiring higher current density must use the Samtec part.

Contact Finish: The Samtec part features tin plating on mating contacts, while the 3M part features gold plating. Gold-plated contacts provide enhanced corrosion resistance and lower contact resistance in low-signal applications.

Insulation Material: The Samtec part uses Liquid Crystal Polymer (LCP), while the 3M part uses glass-filled PCT. Both materials meet UL94 V-0 flammability requirements and operate across the specified temperature range.

Packaging and Availability: The Samtec part is supplied in tube packaging with 654 units in stock. The 3M part is supplied in cut tape with 1492 units in stock, offering higher availability for high-volume production.

Compliance: Both parts are RoHS compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the N2530-6V0C-RB-WF directly replace the HTST-115-01-T-DV in existing designs?

A: Direct mechanical and electrical substitution is valid for applications where the 1.75A per-contact current rating of the 3M part meets design requirements. If the application requires the 3.4A per-contact rating of the Samtec part, substitution is not recommended.

Q: What are the dimensional differences between these two connectors?

A: The contact length mating dimension differs by 0.007" (0.18mm), with the Samtec part at 0.250" (6.35mm) and the 3M part at 0.243" (6.17mm). The insulation height differs by 0.040" (1.02mm), with the 3M part at 0.390" (9.91mm) versus the Samtec part at 0.350" (8.89mm). These differences may affect mating depth and overall assembly height.

Q: Are there differences in contact finish that affect performance?

A: The Samtec part uses tin plating on mating contacts, while the 3M part uses gold plating with 30.0µin (0.76µm) thickness. Gold plating provides superior corrosion resistance and lower contact resistance, particularly beneficial in environments with high humidity or corrosive atmospheres.

Q: Which part should be selected for high-volume production?

A: The N2530-6V0C-RB-WF offers higher inventory availability (1492 units) and is supplied in cut tape format, which is optimized for automated pick-and-place assembly. The HTST-115-01-T-DV is supplied in tube packaging with lower current inventory levels.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts meet UL94 V-0 flammability rating, operate across -55°C to 105°C, and are RoHS compliant. Both carry EAR99 ECCN and identical HTSUS classifications, ensuring regulatory equivalence for export and compliance purposes.
