Engineering Selection Recommendations

Primary Substitute: A-TB500-OP17 (Assmann WSW Components)

The A-TB500-OP17 is the preferred substitute for the obsolete TE Connectivity 1-282832-8. This part maintains identical mechanical dimensions, pitch, position count, and mounting configuration. The A-TB500-OP17 is active in production status with ROHS3 compliance and REACH unaffected certification. The current rating of 10A is within acceptable operational parameters for most applications, and the extended operating temperature range (-40°C to 115°C) provides additional thermal margin. Packaging is available in bulk format.

Secondary Substitute: ESZH17160 (Amphenol PCD)

The ESZH17160 provides full electrical and mechanical compatibility with identical current rating (12A), voltage specification (300V), and operating temperature range (-40°C to 110°C). This part is active in production with RoHS compliance. The ESZH series offers tray packaging and maintains the same contact tail length and insulation height specifications. Contact material is copper alloy rather than brass, which is functionally equivalent for this application class.

Tertiary Substitutes: OSTOP170000, OSTOP170100, OSTOP170200 (On Shore Technology Inc.)

The OSTOP series parts from On Shore Technology Inc. are active alternatives with ROHS3 compliance and REACH unaffected status. These parts maintain the 17-position, 5.00mm pitch vertical configuration and 300V rating. However, dimensional variations exist:

OSTOP170000: Insulation height 0.138" (3.50mm) versus original 0.079" (2.00mm)
OSTOP170100: Contact tail length 0.169" (4.29mm) versus original 0.138" (3.50mm)
OSTOP170200: Insulation height 0.138" (3.50mm) versus original 0.079" (2.00mm)

These dimensional differences may require PCB layout verification before implementation. Selection of OSTOP series parts is appropriate when board design accommodates the specified dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can the A-TB500-OP17 be used as a direct replacement for the TE Connectivity 1-282832-8 without PCB modification?

A: Yes. The A-TB500-OP17 maintains identical pitch (5.00mm), position count (17), contact tail length (3.50mm), and insulation height (2.00mm). Direct board-level substitution is supported without design modification.

Q: What is the significance of the current rating difference between the original part (12A) and the A-TB500-OP17 (10A)?

A: The A-TB500-OP17 current rating of 10A is lower than the original 12A specification. Applications operating at or below 10A per contact are fully compatible. Applications requiring 12A per contact should select ESZH17160, which maintains the original 12A rating.

Q: Why do the OSTOP series parts show different insulation heights and contact tail lengths?

A: The OSTOP series offers multiple variants within the 17-position, 5.00mm pitch family. OSTOP170000 and OSTOP170200 feature increased insulation height (3.50mm), while OSTOP170100 features extended contact tail length (4.29mm). These variants are designed for specific application requirements. PCB footprint verification is required before selection.

Q: Are all substitute parts RoHS compliant?

A: The A-TB500-OP17 is ROHS3 compliant. The ESZH17160 is RoHS compliant. The OSTOP series (OSTOP170000, OSTOP170100, OSTOP170200) are ROHS3 compliant. All substitutes meet current environmental compliance standards.

Q: What is the difference between the Assmann WSW A-TB500-OP17 and Amphenol PCD ESZH17160 in terms of contact material?

A: The original TE Connectivity part and ESZH17160 use brass contacts. The A-TB500-OP17 contact material is not specified in available documentation. Both materials are suitable for standard terminal block applications. Contact material selection does not affect electrical performance for this component class.

Q: Can OSTOP170100 be used if the PCB design requires extended contact tail length?

A: Yes. The OSTOP170100 provides a contact tail length of 0.169" (4.29mm) compared to the original 0.138" (3.50mm). This extended tail length accommodates deeper PCB plating or specific assembly requirements. Verify that the increased tail length does not interfere with adjacent components or assembly processes.

Q: What packaging options are available for these substitute parts?

A: A-TB500-OP17 is available in bulk packaging. ESZH17160 is available in tray packaging. OSTOP series parts are available in bulk packaging. Packaging selection should align with production volume and handling requirements.

Q: Is the operating temperature range difference between A-TB500-OP17 (-40°C to 115°C) and the original part (-40°C to 110°C) significant?

A: The A-TB500-OP17 provides an extended upper temperature limit of 115°C versus the original 110°C. This represents a 5°C thermal margin increase and is beneficial for applications operating in elevated temperature environments. Applications within the original -40°C to 110°C range are fully supported.
