Substitute Part Grouping Explanation

Substitution of the UBA-4R-S14H-2(LF)(SN) is determined by strict equivalence across the following critical parameters:

• Connector Type: USB-A (USB TYPE-A) receptacle configuration
• Contact Count: 4-position
• Gender: Receptacle
• Mounting Configuration: Surface mount with right-angle, horizontal orientation and through-hole capability
• Electrical Ratings: 1A current capacity, 30VAC/DC voltage rating
• Environmental Specifications: Operating temperature range -55°C ~ 85°C, shielded construction
• Material & Compliance: Gold-plated contacts, copper alloy shielding, UL94 V-0 flammability rating, ROHS3 compliance

The substitute part UBA-4R-S14H-4S maintains full equivalence across all critical parameters while offering active product status and USB 2.0 specification compliance.

Parameter Comparison

Engineering Selection Recommendations

The UBA-4R-S14H-4S is a direct functional equivalent to the obsolete UBA-4R-S14H-2(LF)(SN). Both parts share identical electrical ratings, mechanical mounting configurations, and environmental operating parameters. The substitute part maintains ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory continuity in applications requiring these standards.

The primary distinction is product status: UBA-4R-S14H-4S is active and available for procurement, whereas UBA-4R-S14H-2(LF)(SN) is obsolete. The substitute part additionally specifies USB 2.0 compliance, providing enhanced specification clarity for modern USB connectivity applications.

Frequently Asked Questions (FAQ)

Q: Can UBA-4R-S14H-4S replace UBA-4R-S14H-2(LF)(SN) in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 4-position USB-A receptacle, 1A current rating, 30VAC/DC voltage rating, surface mount right-angle horizontal mounting, shielded construction with gold-plated contacts, and identical operating temperature range (-55°C ~ 85°C). Footprint and pinout compatibility is maintained.

Q: What is the significance of the product status difference?

A: UBA-4R-S14H-2(LF)(SN) is classified as obsolete, indicating discontinued manufacturing and limited availability. UBA-4R-S14H-4S is active, ensuring reliable long-term procurement and supply chain continuity for new designs and production runs.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance certifications: ROHS3 compliance and UL94 V-0 flammability rating. Moisture sensitivity level is equivalent at MSL 1 (Unlimited) for both parts.

Q: Does the USB 2.0 specification on UBA-4R-S14H-4S affect compatibility?

A: No. USB 2.0 specification on the substitute part represents enhanced documentation clarity and does not alter electrical or mechanical compatibility. The 4-position USB-A receptacle configuration and electrical ratings remain identical.

Q: Are packaging considerations relevant for substitution?

A: Packaging format differences do not affect functional substitution. Both parts are suitable for surface mount assembly with through-hole capability in horizontal right-angle orientation. Verify packaging availability (bulk vs. other formats) based on procurement requirements.
