Phoenix Contact 3003745 Terminal Block Ground Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3003745 is a 2-position ground terminal block connector designed for wire gauges 14-26 AWG (0.14-2.5 mm²). This component belongs to the CLIPLINE MZB series and features push-in spring termination with polyamide insulation rated UL94 V-0. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3003745 is determined by the following critical parameters:

Core Compatibility Criteria:

• Number of positions: 2 (fixed requirement)
• Number of levels: 1 (fixed requirement)
• Terminal width: 5.2 mm (fixed requirement)
• Termination style: Push In, Spring (fixed requirement)
• Type: Ground, Earth (functional requirement)
• Material insulation: Polyamide (PA), Nylon (fixed requirement)
• Material flammability rating: UL94 V-0 (fixed requirement)
• Color: Green, Yellow (fixed requirement)

Allowable Variation Parameters:

• Wire gauge range: Substitute must accommodate the original 14-26 AWG range or extend it
• Wire gauge range (mm²): Substitute must accommodate the original 0.14-2.5 mm² range or extend it
• Stripping length: Minor variation acceptable within standard engineering tolerances
• RoHS/REACH compliance: Substitute must maintain or exceed compliance level
• Product status: Active status preferred for availability

The Phoenix Contact 3209536 qualifies as a direct substitute because it maintains all core compatibility criteria while extending the wire gauge acceptance range to 12-26 AWG (0.14-4 mm²), providing enhanced flexibility for component selection.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3209536 is the qualified substitute for the obsolete 3003745. Both components maintain identical mechanical and electrical specifications for the core functional requirements: 2-position ground terminal block with push-in spring termination, 5.2 mm terminal width, and UL94 V-0 polyamide insulation.

The 3209536 offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended wire gauge acceptance range (12-26 AWG versus 14-26 AWG) provides design flexibility
• ROHS3 compliance represents current regulatory alignment
• Identical termination method and physical form factor ensure direct mechanical compatibility
• Stripping length increase from 9 mm to 10 mm falls within standard engineering tolerances for push-in terminal applications

Both components carry identical RoHS and REACH compliance designations and share the same ECCN and HTSUS classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 3209536 be used as a direct replacement for the 3003745 in existing designs?

A: Yes. The 3209536 maintains all critical mechanical and electrical parameters. The extended wire gauge range and increased stripping length represent enhancements rather than deviations from the original specification.

Q: What is the significance of the wire gauge range extension from 14-26 AWG to 12-26 AWG?

A: The substitute accepts smaller wire gauges (12 AWG and 13 AWG) in addition to the original range. This does not affect compatibility with the original 14-26 AWG specification, as all original wire sizes remain within the substitute's acceptance range.

Q: Does the 1 mm increase in stripping length (9 mm to 10 mm) affect installation procedures?

A: No. The stripping length increase is a minor variation within standard engineering tolerances for push-in spring terminal blocks. Installation procedures remain unchanged.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain RoHS and REACH compliance. The 3209536 carries ROHS3 designation, representing current regulatory standards. Both share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Q: Why is the 3003745 listed as obsolete?

A: The 3003745 belongs to the CLIPLINE MZB series, which has been superseded by the CLIPLINE PT series. The 3209536 represents the current production equivalent within Phoenix Contact's terminal block portfolio.

Q: Is packaging a consideration for substitution?

A: The 3209536 is supplied in box packaging. Verify packaging requirements for your application, as this may affect inventory management and handling procedures.
