EF2-D30-1 Terminal Block Equivalent & Substitute Parts

Part Overview

The EF2-D30-1 is a 1-position terminal block from Hirose Electric's ZERO SCREW™ EF2 series, designed for DIN rail mounting applications. This component features a black busbar configuration with push-in spring termination, rated for 600V UL and operating temperatures from -25°C to 105°C. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain system compatibility and ensure continued availability for new installations and replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EF2-D30-1 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Compatibility Parameters:

• Manufacturer: Hirose Electric Co Ltd (same manufacturer ensures design consistency)
• Series: ZERO SCREW™ EF2 (maintains mechanical and electrical interface compatibility)
• Terminal Width: 17.5mm (ensures physical fit in existing DIN rail installations)
• Termination Style: Push In, Spring (maintains connection methodology)
• Voltage Rating: 600V UL (meets or exceeds electrical requirements)
• Wire Gauge Range: 1.25-5.5mm² (supports identical conductor sizes)
• Mounting Type: DIN Rail (preserves installation method)
• Material - Insulation: Modified Polyphenylene Ether (M-PPE) (maintains thermal and chemical properties)
• Flammability Rating: UL94 V-0 (ensures safety compliance)
• Operating Temperature: -25°C ~ 105°C (maintains thermal operating envelope)

The primary difference between the main part and substitute alternatives is the number of positions. The EF2-D30-1 provides a single position, while substitute parts in this series offer multiple positions. Selection depends on circuit requirements and available space within the DIN rail installation.

Parameter Comparison

Engineering Selection Recommendations

The EF2-D30BA-1 is the active equivalent substitute for the obsolete EF2-D30-1. Both components maintain identical electrical ratings (600V UL), thermal operating range (-25°C to 105°C), insulation material (M-PPE), and flammability certification (UL94 V-0). Both are RoHS compliant with MSL rating 1, ensuring regulatory and environmental compliance.

The EF2-D30BA-1 is currently in active production status with confirmed inventory availability, whereas the EF2-D30-1 is obsolete. The primary design difference is the number of positions: the substitute provides 2 positions compared to the main part's single position. This difference must be evaluated against circuit requirements and available DIN rail space in the target application.

All mechanical parameters remain consistent: 17.5mm terminal width, push-in spring termination, DIN rail mounting, and identical physical dimensions (length 57.60mm, height 47.20mm). The substitute maintains full compatibility with the same wire gauge range (1.25-5.5mm²) and housing color (black).

Frequently Asked Questions (FAQ)

Q: Can the EF2-D30BA-1 directly replace the EF2-D30-1 in existing installations?

A: The EF2-D30BA-1 is mechanically and electrically compatible with the EF2-D30-1 for DIN rail mounting. The primary consideration is the difference in position count: the substitute provides 2 positions versus the original's single position. Physical dimensions and electrical ratings are identical. Verify that available DIN rail space accommodates the 2-position configuration.

Q: What determines compatibility between these terminal blocks?

A: Compatibility is determined by matching parameters: manufacturer (Hirose Electric), series (ZERO SCREW™ EF2), terminal width (17.5mm), termination style (push-in spring), voltage rating (600V), wire gauge range (1.25-5.5mm²), mounting type (DIN rail), insulation material (M-PPE), and operating temperature range (-25°C to 105°C).

Q: Why is the EF2-D30-1 classified as obsolete?

A: The EF2-D30-1 is no longer in active production. The EF2-D30BA-1 represents the current active alternative within the same ZERO SCREW™ EF2 series, offering equivalent electrical and mechanical performance with continued manufacturer support and availability.

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

A: Both parts maintain identical compliance certifications: RoHS compliant, UL94 V-0 flammability rating, 600V UL voltage rating, and MSL rating 1. No compliance gaps exist between the main part and substitute.

Q: What is the wire gauge compatibility range?

A: Both the EF2-D30-1 and EF2-D30BA-1 support wire gauges from 1.25mm² to 5.5mm², ensuring identical conductor compatibility across the substitution.
