Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1-1622824-5 is determined by strict equivalence across the following critical parameters: resistance value (620 mOhms), tolerance (±1%), package type (2512 / 6432 Metric), composition (thick film), and application feature (current sense). Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must remain consistent.

Substitute parts are grouped into two categories:

Direct Equivalents: Parts maintaining identical electrical specifications, power rating (1W), and package dimensions. These include TE Connectivity 4-1622824-3 and RL73H3AR62FTDF, both active products with full parameter alignment.

Enhanced Substitutes: Parts exceeding the original specification in power rating or compliance certifications while maintaining core electrical parameters. The Vishay Dale RCWE2512R620FKEA provides 2W power rating and automotive AEC-Q200 qualification, suitable for applications requiring higher thermal margin or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

The TE Connectivity 4-1622824-3 provides the most direct equivalent to the obsolete 1-1622824-5. Both parts share identical electrical parameters (620 mOhms, ±1%, 1W, ±100ppm/°C) and package configuration. The 4-1622824-3 is active and available in Tape & Reel packaging. This part carries ROHS3 compliance, meeting current regulatory requirements. Selection of 4-1622824-3 is appropriate for applications requiring exact specification matching without design modification.

The TE Connectivity RL73H3AR62FTDF offers equivalent electrical performance and is available in high inventory volume (26,083 pcs). This part maintains all core specifications and operates within the same temperature range. The RL73H3AR62FTDF is classified as RoHS non-compliant; selection requires confirmation that RoHS compliance is not a design requirement.

For Enhanced Performance:

The Vishay Dale RCWE2512R620FKEA provides a 2W power rating compared to the original 1W specification, offering increased thermal margin in current sense applications. This part carries AEC-Q200 automotive qualification and ROHS3 compliance. The RCWE2512R620FKEA is suitable for designs requiring automotive-grade reliability or applications with higher power dissipation margins. Physical dimensions remain compatible with 2512 package footprints.

Compliance Considerations:

Applications requiring ROHS3 compliance should utilize either 4-1622824-3 or RCWE2512R620FKEA. Applications with REACH compliance requirements should avoid RL73H3AR62FTDF (REACH status vendor undefined) and select from 1-1622824-5, 4-1622824-3, or RCWE2512R620FKEA (all REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-1622824-3 be used as a direct replacement for the obsolete 1-1622824-5?

A: Yes. The 4-1622824-3 maintains identical electrical specifications (620 mOhms ±1%, 1W, ±100ppm/°C) and package configuration (2512 / 6432 Metric). Both parts are thick film current sense resistors with identical operating temperature ranges (-55°C ~ 155°C) and moisture sensitivity levels. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk).

Q: What is the difference between the RL73H3AR62FTDF and the 4-1622824-3?

A: Both parts are TE Connectivity products with identical electrical specifications and package type. The RL73H3AR62FTDF is available in significantly higher inventory volume (26,083 pcs vs. 779 pcs). The 4-1622824-3 carries ROHS3 compliance certification, while the RL73H3AR62FTDF is RoHS non-compliant. Selection depends on regulatory requirements and inventory availability.

Q: Why would the Vishay Dale RCWE2512R620FKEA be selected over TE Connectivity alternatives?

A: The RCWE2512R620FKEA provides a 2W power rating, double that of the original 1W specification. This higher power rating allows increased current sense capability and thermal margin. The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Selection is appropriate for automotive applications or designs requiring enhanced reliability and thermal performance.

Q: Are all substitute parts compatible with the original 2512 package footprint?

A: Yes. All substitute parts use the 2512 (6432 Metric) package configuration. Physical dimensions are compatible with existing PCB layouts. Minor variations in seated height (ranging from 0.026" to 0.028") do not affect footprint compatibility or assembly processes.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by resistance value (620 mOhms), tolerance (±1%), package type (2512 / 6432 Metric), composition (thick film), and application feature (current sense). Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must remain consistent. Power rating may be equal or higher. All parts must maintain two terminations and MSL 1 rating.

Q: Can the 2W-rated RCWE2512R620FKEA be used in applications originally designed for 1W?

A: Yes. The RCWE2512R620FKEA exceeds the original power specification and maintains all electrical parameters. Higher power rating provides additional thermal margin and does not create incompatibility. The part is suitable for direct substitution in applications originally specified for 1W operation.

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

A: The obsolete 1-1622824-5 is supplied in bulk packaging. All active substitutes (4-1622824-3, RL73H3AR62FTDF, RCWE2512R620FKEA) are supplied in Tape & Reel (TR) format, standard for automated assembly processes.
