Key Parameters

Substitute Part Grouping Explanation

Substitution of the EM221508V is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of positions (must be 8)
• Pitch specification (5.00mm or 5.08mm acceptable with design verification)
• Header orientation (vertical only)
• Termination style (solder)
• Mounting type (through hole)
• Voltage rating (minimum 300V UL)
• Current rating (minimum 16A UL or equivalent IEC rating)
• Flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

Secondary Variation Parameters:

• Shrouding configuration (2-side or 4-side acceptable depending on application)
• Contact material (brass or copper alloy acceptable)
• Housing material (thermoplastic, polyamide, nylon, or PBT acceptable)
• Operating temperature range (must encompass application requirements)
• Contact tail length (mechanical fit dependent)

Substitutes are grouped by pitch specification: 5.00mm pitch parts and 5.08mm pitch parts. Parts with 4-side shrouding provide direct mechanical replacement. Parts with 2-side shrouding offer functional equivalence with different mechanical profiles.

All listed substitutes maintain ROHS3 compliance and UL94 V-0 flammability rating. Selection between 5.00mm and 5.08mm pitch variants requires verification of PCB layout and mating connector specifications. Selection between 2-side and 4-side shrouding depends on mechanical space constraints and application requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 5.08mm pitch part for the 5.00mm EM221508V?

A: Substitution between 5.00mm and 5.08mm pitch parts requires verification of PCB layout and mating connector compatibility. These pitch specifications are not interchangeable without design modification. The 0.08mm difference affects board spacing and connector alignment.

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

A: 4-side shrouding provides complete enclosure on all four sides of the terminal block header, offering maximum protection and mechanical stability. 2-side shrouding provides enclosure on two opposing sides. The EM221508V features 4-side shrouding. Substitution to 2-side shrouding parts alters the mechanical profile and may affect mounting stability depending on application design.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance status, matching the EM221508V specification.

Q: Do all substitute parts meet the 16A current rating of the EM221508V?

A: No. Phoenix Contact parts 1753550 and 1758076 are rated at 12A UL. TE Connectivity 282822-8 and Amphenol PCD ELFH08250 are rated at 15A UL. Amphenol Anytek OQ0853500000G is rated at 12A UL. Würth Elektronik parts 691311500008 and 691311700008 are rated at 20A UL, exceeding the EM221508V specification. Application current requirements must be verified before substitution.

Q: What is the operating temperature range consideration for substitution?

A: The EM221508V operates from -55°C to 105°C. Most substitute parts operate from -40°C to 105°C or -40°C to 110°C, which does not extend to the lower -55°C limit. EDSTL955/8 operates from -30°C to 105°C. Applications requiring operation below -40°C must verify substitute part suitability.

Q: Are the contact materials interchangeable?

A: The EM221508V uses brass contacts. Substitute parts use brass or copper alloy contacts. Both materials are acceptable for general terminal block applications. Specific application requirements for contact material should be verified.

Q: What housing material differences exist among substitutes?

A: The EM221508V uses thermoplastic housing. Substitute parts use polyamide (PA), nylon, polybutylene terephthalate (PBT), or thermoplastic resin. All materials carry UL94 V-0 flammability rating. Material selection affects mechanical properties and environmental resistance; application-specific requirements should be verified.

Q: Do all substitute parts have the same contact tail length?

A: No. Contact tail length varies among substitutes. The EM221508V has a contact tail length of 0.177" (4.50mm). Substitute parts range from 0.138" to 0.157" (3.50mm to 4.00mm). Shorter tail lengths may affect solder joint formation on PCBs with specific design requirements.

Q: Can I use EDSTL955/8 as a direct replacement for EM221508V?

A: EDSTL955/8 provides identical 4-side shrouding and 5.00mm pitch configuration. However, current rating is not specified in available documentation, and operating temperature range is -30°C to 105°C, which does not extend to the EM221508V lower limit of -55°C. These differences must be evaluated against application requirements.

Q: What compliance certifications are common to all parts?

A: All listed parts carry ROHS3 compliance and UL94 V-0 flammability rating. All parts are rated at 300V UL voltage. These specifications are consistent across all substitutes.
