Phoenix Contact 3003787 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3003787 is a 2-position terminal block from the CLIPLINE MZB series, designed for direct mount applications with push-in spring termination. This middle-type terminal block features a 5.2mm terminal width and supports wire gauges from 14-26 AWG (0.14-2.5mm²). The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3003787 is determined by the following critical parameters:

• Mechanical Compatibility: Type (Middle), mounting method (Direct Mount), number of positions (2), terminal width (5.2mm), and physical dimensions (32.00mm length, 22.00mm max height)
• Electrical Compatibility: Termination style (Push In, Spring), wire gauge support range, current and voltage ratings
• Material & Compliance: Polyamide insulation, UL94 V-0 flammability rating, and RoHS compliance status

The substitute part Phoenix Contact 3249062 meets these criteria through equivalent mechanical form factor, compatible termination technology, and superior electrical ratings that maintain or exceed the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3249062 serves as a direct substitute for the obsolete 3003787 based on the following engineering criteria:

Mechanical Equivalence: Both parts share identical form factors (32.00mm length, 22.00mm maximum height), terminal width (5.2mm), and mounting configuration (Direct Mount, Middle type, 2 positions). PCB layout and mechanical integration remain unchanged.

Electrical Compatibility: The 3249062 provides enhanced electrical performance with IEC current rating of 24 A versus 17.5 A, while maintaining the same 800 V IEC voltage specification. The expanded wire gauge range (12-28 AWG, 0.08-4mm²) accommodates a broader conductor spectrum compared to the original 14-26 AWG specification.

Compliance Status: The 3249062 maintains UL94 V-0 flammability certification and advances to ROHS3 compliance, meeting current regulatory requirements. The active product status ensures long-term availability and supply chain continuity.

Design Consideration: The UL voltage rating of the 3249062 is 300 V compared to 600 V on the original part. Applications requiring 600 V UL compliance must evaluate this parameter against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3249062 be used as a direct replacement for the 3003787 in existing designs?

A: Yes, for applications operating within the 3249062 electrical specifications. Mechanical compatibility is confirmed through identical dimensions and terminal width. Verify that your application does not require the 600 V UL rating, as the substitute provides 300 V UL specification.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), enhanced current ratings on the substitute (24 A IEC versus 17.5 A), expanded wire gauge support (12-28 AWG versus 14-26 AWG), and UL voltage rating (300 V versus 600 V). Both maintain identical physical dimensions and push-in spring termination technology.

Q: Are there any compatibility concerns with PCB mounting?

A: No. Both parts feature identical 32.00mm length and 22.00mm maximum height with direct mount configuration. Existing PCB footprints and mounting holes require no modification.

Q: Does the wire gauge expansion on the 3249062 affect termination reliability?

A: The expanded range (0.08-4mm² versus 0.14-2.5mm²) reflects the enhanced current capacity of the substitute part. Wire termination reliability is maintained through the same push-in spring mechanism used in both designs.

Q: What is the significance of the ROHS3 compliance on the 3249062?

A: ROHS3 compliance indicates adherence to current Restriction of Hazardous Substances regulations. This ensures the part meets modern environmental and material safety standards required for new equipment certifications and procurement specifications.

Q: Can the 3249062 handle higher current applications than the original part?

A: Yes. The 3249062 is rated for 24 A at IEC specification compared to 17.5 A on the 3003787, providing approximately 37% higher current capacity while maintaining the same 800 V voltage rating.
