USB3145-30-0-A Equivalent & Substitute Parts

Part Overview

The USB3145-30-0-A is a USB micro B receptacle connector manufactured by GCT, designed for through-hole vertical mounting applications. This 5-position connector operates at USB 2.0 specification with a rated voltage of 30VAC and current capacity of 1A to 1.8A. The connector features gold-plated contacts, shielded construction with stainless steel shell material, and UL94 V-0 flammability rating. Currently in active product status with ROHS3 compliance and REACH unaffected classification, this connector is suitable for consumer and industrial electronic assemblies requiring reliable micro USB connectivity.

Alternative part numbers become necessary when addressing supply chain constraints, packaging format requirements, or extended operating temperature ranges for specific application environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB3145-30-0-A is determined by strict equivalence across the following critical parameters: connector type (USB micro B receptacle), contact count (5 positions), mounting configuration (through-hole vertical), termination method (solder), USB specification (2.0), current rating (1A/1.8A), voltage rating (30V minimum), mating cycle durability (10000 cycles), shielding (shielded), contact finish (gold), shell material (stainless steel), flammability rating (UL94 V-0), and regulatory compliance (ROHS3, REACH unaffected).

The four substitute parts listed—USB3130-30-A, USB3131-30-0230-A, USB3145-30-1-A, and 614105150721—meet all core electrical and mechanical parameters. Variations exist only in operating temperature range, packaging format, and moisture sensitivity classification, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status with full ROHS3 compliance and REACH unaffected classification, ensuring regulatory alignment with the main part USB3145-30-0-A.

GCT USB3130-30-A and USB3131-30-0230-A offer extended operating temperature range (-55°C to 85°C) compared to the main part (-30°C to 85°C), providing thermal margin for applications requiring lower temperature operation. USB3131-30-0230-A is available in Cut Tape and Digi-Reel packaging formats, suitable for lower-volume or mixed-component assembly workflows.

GCT USB3145-30-1-A maintains identical operating temperature and voltage specifications as the main part, differing only in moisture sensitivity classification. This variant is available in standard Tape & Reel packaging with higher inventory availability (12,294 units).

Würth Elektronik 614105150721 provides cross-manufacturer equivalence with operating temperature range of -40°C to 85°C and Cut Tape packaging. This part maintains all electrical and mechanical specifications while offering supply diversification from an alternative qualified manufacturer.

Frequently Asked Questions (FAQ)

Q: Can USB3130-30-A or USB3131-30-0230-A be used as direct replacements for USB3145-30-0-A in standard applications?

A: Yes. Both parts meet all core electrical and mechanical parameters: 5-position USB micro B receptacle, through-hole vertical mounting, solder termination, USB 2.0 specification, 1A/1.8A current rating, 30V voltage rating, 10,000 mating cycles, shielded construction with gold-plated contacts, and UL94 V-0 flammability rating. The extended operating temperature range (-55°C to 85°C) provides additional thermal capability without affecting standard room-temperature applications.

Q: What is the difference between USB3145-30-0-A and USB3145-30-1-A?

A: Both parts are from the same USB3145 series with identical electrical specifications, operating temperature range (-30°C to 85°C), and voltage rating (30VAC). The primary difference is moisture sensitivity level classification: USB3145-30-0-A is classified as MSL 1 (Unlimited), while USB3145-30-1-A is classified as Not Applicable. This distinction does not affect functional performance in standard assembly environments.

Q: How does packaging format affect part selection?

A: Packaging format determines assembly workflow compatibility. Tape & Reel (TR) packaging is standard for high-volume automated assembly. Cut Tape (CT) and Digi-Reel formats are suitable for lower-volume production, mixed-component kits, or manual assembly processes. All three packaging formats contain identical connector components with no electrical or mechanical differences.

Q: Is the Würth Elektronik 614105150721 fully compatible with GCT parts?

A: Yes. The 614105150721 meets all functional equivalence criteria: USB micro B receptacle, 5 contacts, through-hole vertical mounting, solder termination, USB 2.0 specification, 1A/1.8A current rating, 30VAC voltage rating, 10,000 mating cycles, shielded construction, gold-plated contacts, and UL94 V-0 rating. Operating temperature range is -40°C to 85°C. Cross-manufacturer substitution is valid for supply chain flexibility.

Q: What parameters must remain constant for substitution eligibility?

A: Connector type (USB micro B receptacle), contact count (5), mounting method (through-hole vertical), termination (solder), USB specification (2.0), current rating (1A/1.8A minimum), voltage rating (30V minimum), mating cycles (10,000), shielding (shielded), contact finish (gold), shell material (stainless steel), and flammability rating (UL94 V-0) must remain unchanged. Operating temperature range, packaging format, and moisture sensitivity level may vary without affecting functional interchangeability.
