Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM221504H is determined by the following critical parameters:

Primary Compatibility Criteria:

• 4-position configuration
• 90° right-angle header orientation
• Through-hole solder termination
• Pitch spacing within 5.00mm to 5.08mm tolerance range
• Voltage rating of 300 V (UL)
• Current rating minimum 15 A (UL)
• Operating temperature range overlap
• UL94 V-0 flammability rating

Acceptable Variations:

• Shrouding configuration (2-side or 4-side)
• Contact material (Brass or Copper Alloy)
• Housing material (Thermoplastic, Polyamide PA66, or Polybutylene Terephthalate PBT)
• Contact mating finish (Tin)
• Color designation

The EM221504H can be substituted with TE Connectivity 282815-4 and Amphenol PCD ELFH04210 based on these parameters. Both alternatives maintain electrical and mechanical compatibility within the specified tolerance ranges.

Engineering Selection Recommendations

EM221504H (Eaton) - Primary Part

Use the original EM221504H when RoHS non-compliance is acceptable for the application and when the extended lower temperature rating (-55°C minimum) is required. This part offers 4-side shrouding and the highest current rating at 16 A.

282815-4 (TE Connectivity) - Substitute Option

Select 282815-4 when RoHS compliance is mandatory and the application operates within -40°C to 110°C temperature range. This part features 2-side shrouding and is suitable for applications where reduced shrouding does not impact performance. Current rating is 15 A, which is acceptable for most standard applications.

ELFH04210 (Amphenol PCD) - Substitute Option

Select ELFH04210 when ROHS3 compliance is required and 4-side shrouding is necessary. This part maintains the same shrouding configuration as the original EM221504H and operates within -40°C to 105°C. Current rating is 15 A. Color is black rather than green.

All three parts share identical electrical specifications (300 V, UL94 V-0), through-hole solder termination, and 4-position configuration. Selection should be based on compliance requirements, temperature range needs, and shrouding preferences.

Frequently Asked Questions (FAQ)

Q: Can EM221504H be directly replaced with 282815-4 or ELFH04210?

A: Yes, both parts are electrically and mechanically compatible substitutes. The EM221504H, 282815-4, and ELFH04210 all feature 4-position configuration, 90° right-angle orientation, solder termination, 300 V voltage rating, and UL94 V-0 flammability rating. Pitch spacing differs slightly (5.00mm vs. 5.08mm), but this falls within acceptable tolerance for standard PCB layouts. Verify shrouding configuration and RoHS compliance requirements for your specific application.

Q: What is the difference between 4-side and 2-side shrouding?

A: 4-side shrouding (EM221504H and ELFH04210) provides insulation on all four sides of the header, offering maximum protection against accidental contact and cross-talk. 2-side shrouding (282815-4) provides insulation on two opposing sides. Both configurations meet UL94 V-0 flammability requirements. Selection depends on PCB layout constraints and application-specific isolation needs.

Q: Are there temperature range limitations when substituting parts?

A: The EM221504H operates from -55°C to 105°C. The 282815-4 operates from -40°C to 110°C, and ELFH04210 operates from -40°C to 105°C. If your application requires operation below -40°C, the original EM221504H is required. For applications within -40°C to 105°C, all three parts are suitable.

Q: What is the significance of RoHS compliance differences?

A: EM221504H is RoHS non-compliant, while 282815-4 is RoHS Compliant and ELFH04210 is ROHS3 Compliant. RoHS compliance is mandatory for products sold in the European Union and for many OEM supply chains. Select a RoHS-compliant substitute (282815-4 or ELFH04210) if your application or customer requirements mandate RoHS compliance.

Q: Does the current rating difference (16 A vs. 15 A) affect substitution?

A: The EM221504H is rated for 16 A, while both substitutes are rated for 15 A. For applications requiring the full 16 A capacity, the original EM221504H is recommended. For applications operating at 15 A or below, both substitutes are suitable. Verify your circuit current requirements before selecting a substitute part.

Q: Can I use ELFH04210 if color coding is important?

A: ELFH04210 is black, while EM221504H and 282815-4 are green. If color coding is used for circuit identification or assembly documentation, this difference must be noted. Electrically and mechanically, the black color does not affect performance.

Q: What contact material differences exist between these parts?

A: EM221504H and ELFH04210 use brass contacts, while 282815-4 uses copper alloy contacts. Both materials provide equivalent electrical conductivity and tin mating finish. Contact material selection does not affect substitution compatibility for standard applications.
