A-TB500-OP15 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The A-TB500-OP15 is a 15-position terminal block header manufactured by Assmann WSW Components, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as an active product and serves as a connector interface for electrical termination in industrial and electronic applications. The need to identify equivalent and substitute parts arises from inventory availability, lead time considerations, and regional supplier variations while maintaining identical functional and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-TB500-OP15 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 15 positions at 0.197" (5.00mm) spacing
• Physical Configuration: Vertical orientation, through-hole mounting, male pins, unshrouded design
• Electrical Ratings: Minimum voltage rating of 300 V (UL), minimum current rating of 10 A (UL)
• Termination Method: Solder termination
• Mechanical Dimensions: Contact tail length 0.138" (4.60mm), insulation height 0.079" (2.00mm)
• Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1

The substitute part 1933312 (Phoenix Contact COMBICON PST series) meets all critical substitution criteria. This part maintains identical position count, pitch, orientation, mounting type, and physical dimensions. Electrical ratings exceed the minimum requirements, and compliance certifications align with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the A-TB500-OP15 and substitute part 1933312 are active products with current manufacturing status and full compliance with ROHS3 and relevant safety standards. The substitute part demonstrates equivalent or superior electrical performance across all rated parameters. The Phoenix Contact 1933312 provides additional IEC electrical ratings (12 A at 400 V) beyond the UL specifications of the original part, indicating enhanced capability within the same physical form factor.

Selection between these parts should be based on:

• Availability and Lead Time: Current inventory levels and supplier delivery schedules
• Supplier Preference: Established relationships with Assmann WSW Components or Phoenix Contact
• Regional Compliance: Verification that IEC or UL ratings align with end-application requirements
• Cost Considerations: Unit pricing and total cost of ownership across procurement channels

Both parts maintain identical mechanical compatibility and PCB footprint requirements, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1933312 be used as a direct replacement for the A-TB500-OP15?

A: Yes. The 1933312 maintains identical position count (15), pitch spacing (5.00mm), orientation (vertical), mounting type (through-hole), and physical dimensions (contact tail 4.60mm, insulation height 2.00mm). Electrical ratings meet or exceed the original specification, and compliance certifications are equivalent.

Q: What are the key parameters that determine substitution eligibility?

A: Critical parameters include: 15-position configuration, 5.00mm pitch, vertical orientation, through-hole mounting, solder termination, male pins unshrouded, contact tail length 4.60mm, insulation height 2.00mm, UL94 V-0 flammability rating, and ROHS3 compliance. Electrical ratings must meet minimum 300 V (UL) and 10 A (UL) specifications.

Q: Are there differences in housing material between these parts?

A: The A-TB500-OP15 uses thermoplastic housing material. The Phoenix Contact 1933312 specifies polyamide (PA) nylon housing. Both materials meet UL94 V-0 flammability requirements and are suitable for the same electrical and thermal operating conditions.

Q: Do these parts have different operating temperature ranges?

A: The A-TB500-OP15 specifies an operating temperature range of -40°C to 115°C. The Phoenix Contact 1933312 does not provide an operating temperature specification in the available data. For applications requiring confirmed temperature performance, the Assmann WSW part provides explicit thermal rating documentation.

Q: What is the difference in current ratings between these parts?

A: The A-TB500-OP15 is rated for 10 A (UL). The Phoenix Contact 1933312 is rated for 16 A (UL) and 12 A (IEC). The substitute part provides higher current capacity within the same physical package, making it suitable for applications requiring the original 10 A rating and those requiring higher current handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the A-TB500-OP15 and Phoenix Contact 1933312 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity level ratings.
