TE Connectivity 2-282812-4 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-282812-4 is a 24-position terminal block header with male pins, shrouded on two sides, featuring a 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and maintenance applications. The part operates at 15 A (UL) and 300 V (UL) with an operating temperature range of -40°C to 110°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-282812-4 is determined by the following critical parameters that must remain consistent across equivalent parts:

Primary Matching Criteria:

• Number of positions: 24
• Pitch: 0.197" (5.00mm) or 0.200" (5.08mm)
• Header orientation: 90°, right angle
• Termination style: Solder
• Mounting type: Through hole
• Current rating: 15 A (UL)
• Voltage rating: 300 V (UL)
• Material flammability: UL94 V-0
• Contact mating finish: Tin

Secondary Considerations:

• Shrouding configuration (2-side vs. 4-side)
• Housing material composition
• Contact material (copper alloy vs. brass)
• Operating temperature range
• RoHS compliance status

The substitute parts ELFH24120, ELFH24140, and ELFH24210 maintain electrical and mechanical compatibility through matching pitch, position count, current/voltage ratings, and flammability standards. Variations in housing material, contact material, and shrouding configuration represent acceptable engineering alternatives within the terminal block header category.

Parameter Comparison

Engineering Selection Recommendations

ELFH24120 and ELFH24140 Selection: Both ELFH24120 and ELFH24140 maintain identical electrical specifications (15 A UL, 300 V UL) and mechanical configuration (24 positions, 0.197" pitch, 90° right angle, 2-side shrouding, through-hole solder termination) as the obsolete 2-282812-4. These parts are classified as active products with current RoHS compliance. The primary difference between these two substitutes is housing material composition: ELFH24120 uses polybutylene terephthalate (PBT), while ELFH24140 uses polyamide (PA46). Both materials meet UL94 V-0 flammability requirements. The operating temperature range for both substitutes is -40°C to 105°C, which is 5°C lower than the original part's maximum of 110°C. Contact material differs from the original (brass versus copper alloy), but both materials provide equivalent electrical performance at the specified current and voltage ratings.

ELFH24210 Selection: The ELFH24210 represents an alternative with enhanced shrouding (4-side versus 2-side) and a slightly different pitch specification (0.200" or 5.08mm versus 0.197" or 5.00mm). This part maintains all critical electrical parameters (15 A UL, 300 V UL) and is an active product with RoHS compliance. The 4-side shrouding provides additional mechanical protection compared to the original 2-side configuration. The pitch variation of 0.02" (0.08mm) may require PCB layout verification for direct substitution in existing designs.

All three substitute parts are active products with current RoHS compliance, eliminating obsolescence risk and ensuring long-term availability for production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can ELFH24120 or ELFH24140 be used as direct replacements for the 2-282812-4?

A: Yes. Both ELFH24120 and ELFH24140 maintain identical electrical ratings (15 A UL, 300 V UL), position count (24), pitch (0.197" or 5.00mm), orientation (90° right angle), shrouding configuration (2-side), and termination method (solder through-hole). The primary differences are housing material composition and a 5°C reduction in maximum operating temperature (105°C versus 110°C). These differences do not affect functional compatibility in standard applications.

Q: What is the difference between ELFH24120 and ELFH24140?

A: ELFH24120 and ELFH24140 are electrically and mechanically identical. The distinction is housing material: ELFH24120 uses polybutylene terephthalate (PBT), while ELFH24140 uses polyamide (PA46). Both materials meet UL94 V-0 flammability standards. Material selection depends on specific environmental and thermal requirements of the application.

Q: Is ELFH24210 compatible with the 2-282812-4?

A: ELFH24210 maintains electrical compatibility (15 A UL, 300 V UL) and position count (24). However, the pitch differs slightly (0.200" or 5.08mm versus 0.197" or 5.00mm), and shrouding is enhanced (4-side versus 2-side). The pitch variation of 0.02" (0.08mm) requires PCB layout verification before substitution in existing designs. The enhanced 4-side shrouding provides additional mechanical protection.

Q: What is the significance of the operating temperature difference between the main part and substitutes?

A: The 2-282812-4 operates to 110°C maximum, while ELFH24120, ELFH24140, and ELFH24210 operate to 105°C maximum. This 5°C difference is within typical thermal design margins for most applications. Applications requiring operation above 105°C require confirmation that the substitute part meets specific thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 2-282812-4 is ROHS3 compliant. All three substitute parts (ELFH24120, ELFH24140, ELFH24210) are RoHS compliant, ensuring compatibility with RoHS-regulated supply chains and end-use applications.

Q: What packaging formats are available for the substitute parts?

A: ELFH24120 and ELFH24140 are supplied in tray packaging. ELFH24210 is supplied in bulk packaging. Packaging format selection depends on production volume and inventory management requirements.

Q: Do the substitute parts have different contact materials?

A: Yes. The 2-282812-4 uses copper alloy contacts, while ELFH24120, ELFH24140, and ELFH24210 use brass contacts. Both materials provide equivalent electrical performance at the specified 15 A and 300 V ratings with tin mating finish.
